Question

Quizplus · Accepted Answer

Active transport of potassium is not associated with the formation of a nerve impulse. Nerve impulses are generated by changes in the membrane potential caused by the movement of ions across the membrane, specifically the sudden diffusion of sodium ions into the cell, threshold stimulus, and depolarization of the cell membrane segment. These events cause the inside of the cell membrane to become more positive, leading to the formation of a nerve impulse. Active transport of potassium helps to restore the resting potential after the impulse is transmitted.
